Extinction Chess, No White Captures

  • It is not enough just to arrange somehow the white pieces around the four black pieces. For example, the following is not a solution: 1.Rc8-b8 2.Rb8-b3 3.Kd3-c4 4.Be4-b1 5.Sf2-d3 6.Rh2-c2 7.Qe8-f8 8.Sc6-d8 9.Qa6-f6 10.Kd5-d6. Also note that in the solution the pieces around the black rooks and bishops are arranged precisely in the same order.
  • There is also an interesting try to switch the roles of Qe8 and Bg8, which almost succeeds. The pieces can be arranged in 10 moves (Bg8-b3, Kd3-c4, Be4-b1, Sf2-d3, Rh2-c2, Qe8-g8, Rc8-f8, Sc6-d8, Qa6-f6, Kd5-d6), but these moves cannot be ordered properly!
  • Extinction Chess was invented by R. Wayne Schmittberger in 1985 (under the name Survival of the Species), and was mentioned in his 1992 book "New Rules for Classic Games" (ISBN 0-471-53621-0). The first player who does not have pieces of all types loses the game, and a side is in check if it is threatened to lose the last piece of its kind. Pawns may promote to any other type of piece, including Kings. Castling under or through orthodox check is allowed.

  • 4 x Excelsior, 4 x temporary Madrasi paralysis of a pawn that has just made a double-step and can be captured en-passant and AUW!!
  • Madrasi (invented in 1979 by A. J. Karawatkar): a piece threatened by a piece of the same type but of opposite color is paralyzed and becomes unable to move, capture or give check. Most of the time, two like pieces attack each other mutually, meaning they are both paralyzed (en passant pawn captures are a rare exception to this).
  • Ivan has been exploring the effects of the temporary Madrasi paralysis of a pawn that had just made a double-step and can be captured en-passant for quite some time. Ten years ago he also published in Pat a Mat 29/2000 a very interesting article about Madrasi, focused on this specific effect. The second part of the article was published in Pat a Mat 64/2008.
  • There are other possibilities of non-reciprocal Madrasi paralysis (KöKo, Imitator, neutral pieces etc.); Arnold Beine wrote an article on this topic in Harmonie 75, in September 2003, and the 12th Harmonie TT was dedicated to this.
  • The author writes that he worked for a few years on this idea, trying to find a sound ser-h#, in the end having to settle for this ser-ha=>b version, with mating finale. The challenge for our readers is, of course, to find a ser-h# position encapsulating this idea (4 x Excelsior, 4 x temporary Madrasi "en-passant" paralysis and AUW)!
